Fuel Sender Resistance

I've thrown away my original tanks and senders; can anyone tell me the normal/expected resistance range on the factory fuel sender for an E21?

Is it 74ohm empty/3ohm full?

I've got a GM sender in my fuel cell which is 90ohm empty and ~0ohm full, so just working out what resistor I need to add in parallel with it to scale it from 74-0ohm

Full 4,0-5,4 ohm

Empty 85,7-90,7 ohm
